In this video, I discuss the divisions of the nervous system starting first with the central and peripheral nervous systems, then moving to the subdivisions of the peripheral nervous system: the autonomic and somatic nervous systems. I cover the three divisions of the autonomic nervous system: the parasympathetic, sympathetic, and enteric divisions. In the first half of the video, I provide an overview of these systems, and in the latter half I discuss the anatomy and physiology of the peripheral nervous system more in depth.
Key points:
00:00 Introduction
00:38 Central nervous system
1:05 Peripheral nervous system
2:27 Somatic nervous system
2:53 Autonomic nervous system
3:55 Sympathetic nervous system
4:48 Parasympathetic nervous system
5:42 Enteric nervous system
6:58 Somatic nervous system anatomy
8:26 Autonomic nervous system anatomy & physiology

Thank you for making a longer neuroscience video! This is very helpful to understand the organization of the nervous system!

I am about to finish my BA in psychology. The next step is a master's in counseling and mental health. I was a horrible student during my K-12 years, but I have a 3.7 GPA in college. I love these videos because they are short and to the point. I am the type of person who has to see all the parts of the machine to be able to really understand it! Keep it simple and short!

Thank you so much, sir! I watched all of the videos in this channel in about 3 to 4 days. I retained a fair bit in memory. I plan to rewatch it. This is as good as it gets. I love these videos so much! Keep up all the great work. We are all making a difference in each others' lives. A treasure trove of lectures. I have the book your brain, explained. I have to finish it as soon as possible. Yet to buy bizarre. But, after watching these videos I have a good grasp of the basics.

@@neurochallenged I have one question, sir. Can you go deeper into neuroscience to cover some of the difficult concepts in neurochemistry like neurotransmitters and their functions. The basics are crystal clear. I wish you would ramp up the difficulty. I love the presentation style of your videos. Maybe you can fit these difficult concepts into 10-minute neuroscience topic videos rather than 2-minute ones. I'm sorry to bother you with my suggestion, sir. Keep up the good work!

Nice boards! I love the short style lecture videos, I think they are super helpful. I’m currently watching AK Lectures to help prep for MCAT but will be adding this to my content review as well! Great video as always, but if you could step out of frame for one second it would be helpful so I could screenshot the board for notes.

Ah, I hadn't thought about moving out of frame like that---I'll keep it in mind for next time. Thanks!

How is the signal routed when it encounters "junctions"? How does it know where it needs to go?
@xyzyzx1253

This is a property of all neurones. It’s called “summation” into the dendritic tree of the neurone, where if there is enough of a stimulous present across all of the connections that arrived simultaneously at that neurone, it will fire in an “all or nothing” like pattern. Not enough stimulus arriving simultaneously, then no firing. Every neurone is a junction, that has adjustable thresholds depending on the context / previous learning. It’s build into the structure of the neurone, which is then arranged into the large structures you in this lecture. Some nerve fibres (axons) are really long and others are really short, but the junction is called the “synapse”
